This is not my wisdom, this is ordinarily answer to Christmas greeting by Orthodox Christians. Otherwise we are celebrating Christmas on 7th January by Julian calendar 14 days after you are.
So Marry Christmas to you to! Оr in Serbian Cyrillic alphabet :
Срећан Божић, Христос се роди!

Yes, I understand that various
groups of people celebrate at
different times of the year.
Hvala lepo, Marija. May I please
ask ... how does your computer do
that??? I think I need more practice.
I'm just a humble spirit of this
world, awaiting a jolly old man in
a red suit. Thanks for your comment.
